CULTIVATOR.

SPECIFICATION forming peut of Lettere Patent No. 502,171, dated July 25,189e.

Y Application tiled March 31. 1893.

To all whom it may concern:

Be it known that I, ROYER S. BUCH, a citizen of the United States,residing at Elizabethtown, in the county of Lancaster and State ofPennsylvania, have invented a new and useful Cultivator, of which thefollowing is a specification.

My invention relates to improvements in cultivators; the objects in viewbeing to proto vide a cultivator whose frame-work is constructed partlyof gas or water-pipe suitably connected by wrought metal joints orconnections; to` provide -means for adjusting the shovels or scraperblades of the cultivator r 5 whereby they are adapted to operate at andupon the opposite sides of a furrow', and to provide means for adjustingthe handles laterally upon the frame, whereby the operator following thecultivator need not be required 2o to travel or walk in the furrows.

With these and various other objects in View the invention consists incertain other novel features of construction hereinafter specified andparticularly pointed out in the 2 5 claims.

Referring to the drawings-Figure 1 i's a perspective view of acultivator constructed in accordance with my invention. Fig. 2 is avertical sectional View of one of the shovelcarrying standards. Fig. 3is a detail in perspective of one of said standards and a locking keyemployed in connection with the same. Fig. 4is a detail in perspectiveof the angular clamp and standard-supporting bracket em- 3 5 ployed atthe rear angles of the frame.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention I construct a triangular frame, the sameconsisting of the 4o rear pipe 1 and the opposite side pipes 2. The

side pipes 2 converge to form the front angle of a triangle and havetheir front ends embraced by a pair of clamping-plates 3 formed ofwrought-iron. These clampingplates 8 are provided at their ends withsemicircular clamping-portions 4 thatreceive the pipes 2, and at theircenters, the semi-circular clamping-portions 5 that receive the rear endof a draft tongue 6, which may or may 5o not be also constructed ofa'pipe. Through the clamping sections 4 and 5, clamping-bolts Serial No.468.437. (No model.)

7 are passed, whereby these parts are all secured in position.

Pivoted by means of a bolt 8 to the central portion of theclamping-section 5 and to the 55 tongue 6 is the double-tree 9, and tothe ends of the same are attached by links 10 the single-trees 11, ofusual construction. y

A cross-bar 12 surrnounts the side pipes 2, and the ends of thecross-bar are provided 6o with longitudinal slots 13 through which eX-tend the terminals of the pair of inverted U- s shaped clips 14, havingnuts 15 at their extremities above the bar 12. It will be seen that thebar 12 may be adjusted longitudi- 65 nally upon'the side pipes 2 andsecured at any point of its adj ustment by means of the aforesaid nuts15.

An inverted U-shaped clevis 16 is located upon the bar 12 at the centerthereof, and in- 7c serted into the clevis are the front converging endsof a pair of handle-bars 17, which extend upward and rearward from theclevis to points in rear of the frame. A single bolt passes down throughthe clevis and between the handle-bars whereby they are wedged inposition. The rear ends of the handle-bars are connected by means of atransverse rung 18, and said bars are supported or braced by a pair ofinclined braces 8o 19, whose intermediate'portions rest upon the rearpipe 1 of the frame and are pivoted thereto through the medium of thebolt 20. The bar 12, it will be observed, is curved concentric with thepivot bolt 20 so that by loos- 85 ening the nuts 15 of the clips 14 andmoving said bar to the right or left, the handles of the rear ends ofthe handle-bars 17 are disposed either to the right or the left of thecenter of the machine and thus the operator 9o is enabled to follow themachine without walking in the furrow,'at the sides of which shovels,hereinafter mentioned, are operating.

The rear ends of the side pipes 2 are connected to the opposite ends ofthe rear pipe 1 by means of angular clamping sections 21, saidclamping-sections being composed of two U-shaped members whoseinnersides are concaved to fit the pipes. The upper section 21, of eachclamp, is provided at its rear side roo with a horizontal bracket 22,and the same has formed therein at intervals, square openings 23. Bolts24 serve as means for securing the clamping-sections upon the pipes, 1and 2.

V,25 designates standards, of which there are a pair, the said standardsbeing preferably formed of angle iron and provided at their upper endswith reduced cylindrical tenons or studs 26. At their lower ends theyare provided with openings 27 and 28, the latter being formed in a boss29, while around the former opening 27 the flange of the angle iron isspread, as shown at 30. The upper ends of the studs 26 of the standards25 are passed through any one of the openings 23 in the two horizontalbrackets 22, and the said studs are provided at one side each with alongitudinal groove or recess 31. Metal keys 32 are movably tilted inthese openings in which the studs 26 of the standards are inserted andsaid keys are of a length and width adapting them to completely ill theopenings with exception of those portions which are occupied by saidstuds. Each keyis provided upon its inner face with a rib 33 whichcorresponds to the groove 31 ot' the stud, adjacent to which it islocated. By the formation of the studs upon the standards, shoulders34.- are produced at the lower ends or bases of the studsand these takeagainst the under sides of the brackets 22. Above the brackets the studsare threaded, as indicated at 35, and nuts 3G are applied to said endsand serve to bind the shoulders against the brackets so that with theaddition of the keys 32 the standards are'held immovable or rigid inposition and depending from brackets. Of course, the standards may beremoved and reinserted and secured in any one of the series of holes ineach bracket so that the distance apart of the standards may beregulated at will.

By means of heel-bolts 37, triangular shovel or scraper-blades 38 aresecured to the standards, said heel-bolts passing through the openings28 formed in the bosses 29, with which the standards are provided.Eye-bolts 39, having nuts 40, are passed through the upper openings 27of the standards and through the shovels or scraper-blades 38, and links41 are connected to the eye-bolts at their front ends, and by means ofbolts 42 are secured to the side pipes 2. Angular straps 43 are securedto the inner angles of the shovels or blades 38, extend inward towardeach other under the rear pipe 1, overlap, and are connected by means ofthe bolt 2O to the pipe 1. This completes the construction of thecultivator, whose operation is similar to those now in use, it beingobvious that the blades or shovels are constructed to scrape the sidesof a furrow, thus destroying the weeds accumulated thereon; that theadjustment for the shovels may be readily accomplished; that whenadjusted the shovelsare readily held, and finally, that the handles maybe adjusted at the will of the operator whereby 11e may walk at theside, instead of in the furrow, whose sides are being operated upon.

It is to be understood that changes in the form, proportion andthe minordetails of construction may be resorted to without departing from theprinciple or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is 1. In a cultivator, thecombination with a triangular frame, ot a transversely disposed curvedbar mounted upon the side bars of the frame and provided withlongitudinal slots near its ends, clips extending upwardly from theside-bars through the slots and provided with nuts, a pair ot handlebars secured to the transverse bar, and a brace between the handle-barsand rear bar of the frame and pivoted to the latter, concentrically withrelation to the curved bar substantially as specified.

2. In a cultivator, the combination with the triangularly disposedpipes, of the clamping sections embracing the pipes and connecting thesame, the bolts passed through the sec tions and pipes, the uppersections of the rear clamps being provided with horizontal bracketshaving a series of openings, standards removably mounted in theopenings, and blades or shovels secured to the standards, substantiallyas specified.

3. In a cultivator, the combination with the triangularly disposed pipes1 and 2 secured at their front ends, the V-shaped clamping sections 21securing the rear ends of the said pipes to the rear pipe, bolts passingthrough the same, the brackets 22 having rectangular openings 23, thestandards having the shoulders 34, reduced, threaded and grooved tenons26 extending into the openings of the brackets, the keys 32 having theribs 33 fitting the grooves and located in the openings, and the nuts 36threaded on the upper ends of the studs, substantially as specilied.

et. In a cultivator, the combination with the triangular frame, theclamping sections 2l having the brackets provided with openings, thestandards 25 having the spread flange 30, openings 27 and 28, the latterformed in the boss 29, the stud 2G at the upper end of the standard, andmeans t'or securing the same in the openings of the brackets, thetriangular shovels 38, heel-bolts passing through the shovels andopenings 28 of the standards, eye-bolts passing through the shovels andthe openings 27 of the standards, links 41 between the eye-bolts andside bars of the trame, the metal straps 43 secured to the inner anglesof the shovels and overlapping each other under the rear bar of thesame, and the bolt pass ing through the straps and saidbar,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto ai'lixedmy signature in the presence of two Witnesses.
